Of course I find this enabled on the Intel box and not on the AMD one,

From what I have read so far, I'm pretty certain it isn't planned or
even possible to patch this via a microcode update.
Ok, I'm wrong then: I understood Spectre was unfixable, while Intel had
provided (or was going to provide) a microcode update to patch (not
mitigate) MeltDown.
Of course PTI might be a good idea in any case.
For Intel CPUs, there's this list:

Thanks. Altough I was looking for AMD mostly :)
The microcode update itself will work, if that is what you meant, but
just updating the microcode and not FreeBSD is useless to mitigate
Spectre V2.
Again, my fault: the "Please update your system in order to update CPU
microcode." message led me to a wrong conclusion.
bye & Thanks
